Abstract
The utility model relates to a muffler of oxygen and nitrogen generating equipment and comprises a straight cylinder body, wherein, the upper end and the lower end of the straight cylinder body are fixedly connected with a cylinder cap and a cylinder bottom respectively through a threaded bolt; the cylinder cap and the cylinder bottom are detachable terminal plates; one side of the cylinder cap is an outlet, and one side of the cylinder bottom is an inlet; a pollutant discharge port is arranged on the cylinder bottom; a gauze screen is connected to the cylinder bottom; a buffering heated board is additionally arranged on the inner wall of the straight cylinder body. The muffler takes the type of thread disassembly and assembly, the cylinder bottom, the cylinder cap and a muffling filter screen can be disassembled in a short time, and the cleaning is convenient. The buffering heated board is additionally arranged on the inner wall of the straight cylinder body, so that the shakeproof performance is increased, and the muffling performance is further increased, thereby leading the noise grade for generating the oxygen and the nitrogen to fall below 80 decibels. The pollutant discharge port is additionally arranged on the cylinder bottom, so that impurities can be cleared out more directly, the filth blockage probability is further reduced, and the muffling performance is ensured.
Description
Technical field
The utility model relates to system oxygen system nitrogen air separation plant, relates in particular to a kind of system oxygen equipment of making nitrogen sound suppressor that reduces system oxygen equipment of making nitrogen voice.
Background technology
Old-fashioned system oxygen equipment of making nitrogen noise-abatement equipment, it is one-piece type that whole cylindrical shell 1 ' and wire gauze 2 ' are full weldering, as shown in Figure 1, can not dismantle, in case after stopping up, clean quite loaded down with trivial details.Because outer container wall does not cushion warming plate, it is bigger that outer wall produces the impact endurance test shock noise ratio again.Also having a shortcoming is without any blowdown apparatus, in case inside has impurity particle just can't get rid of, stops up noise-abatement equipment easily.
Summary of the invention
The utility model provides a kind of detachable cleaning, antidetonation and acoustic attenuation performance strong system oxygen equipment of making nitrogen sound suppressor in order to solve the problems of the technologies described above.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: the utility model comprises cylindrical shell, is located at the wire gauze in the cylindrical shell, described cylindrical shell was formed by connecting by straight barrel and cover, the tube end, and cover, the tube end are detachable end plate.When needing to clean, can easily cover, the tube end, be pulled down, be convenient to clean.
As preferably, described cover, the tube end and straight barrel are bolted to connection.Make dismounting more convenient, also firm during connection.
As preferably, described straight barrel inwall is provided with the buffering warming plate.Anti-seismic performance is strengthened, and further improves acoustic attenuation performance.
As preferably, the described tube end, be provided with the blowdown interface.The impurity of inner barrel can be discharged by the blowdown interface, reduces dirty stifled probability, guarantees acoustic attenuation performance.
The beneficial effects of the utility model are: cover, the tube end and noise elimination filter net all can be removed in the very fast time, clean very convenient.The straight barrel inwall has installed the buffering warming plate additional, and anti-seismic performance is strengthened, and acoustic attenuation performance also further improves.The tube end, have the blowdown interface, and more directly removal of contamination reduces dirty stifled probability, guarantees acoustic attenuation performance.
Description of drawings
Fig. 1 is the structural representation of old-fashioned system oxygen system nitrogen noise-abatement equipment.
Fig. 2 is a kind of sectional structure synoptic diagram of the present utility model.
Fig. 3 is a kind of plan structure synoptic diagram of the present utility model.
1. straight barrels among the figure, 2. wire gauze, 3. cover, 4. tin at the bottom of, 5. bolt, 6. buffering warming plate, 7. blowdown interface, 8. import, 9. outlet, 1 '. cylindrical shell, 2 '. wire gauze.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: a kind of system oxygen equipment of making nitrogen sound suppressor of present embodiment, as Fig. 2, shown in Figure 3, comprise straight barrel 1, the two ends up and down of straight barrel 1 are fixedly connected with cover 3, the tube end 4 respectively by bolt, and cover 3, the tube end 4 are detachable end plate, and cover one side is outlet 9, the tube end one side is import 8, tube is equipped with a blowdown interface 7 on the end 4, and on 4, the inwall of straight barrel 1 also added one deck buffering warming plate 6 at the bottom of wire gauze 2 was connected tin.
The utility model is a screw thread dismounting type, and cover, the tube end and noise elimination filter net all can be removed in the very fast time, the convenient cleaning.The straight barrel inwall has installed the buffering warming plate additional, and anti-seismic performance is strengthened, and acoustic attenuation performance also further improves, and the sound level of system oxygen system nitrogen is dropped to below 80 decibels.The tube end, installed blowdown apparatus additional, and more directly removal of contamination further reduces dirty stifled probability, guarantees acoustic attenuation performance.
